But if you have to rely on an IDE, it's hard to innovate in language design.

Rust does have rust-analyzer, but it uses piles of RAM and often just doesn't work. I'll periodically try it for a few days and give up on it again. Maybe it's a bug in Kate's LSP support.

I have been using rust-analyzer with vscode (on small programs) and it has been working reliably for me.
